Efflorescence in my garage

My three car garage has several unsightly areas where efflorescence is
blooming out of the concrete floor. I have power-washed the whole floor but
that only increased the efflorescence after the water dried. The
efflorescence is particular bad after I bring a car in from the rain and the
rain water dribbles on the floor.
I know that this problem is only cosmetic but a prospective buyer might be
concerned. I also understand that painting the floor or covering it with
epoxy is counter productive because it will only spall and will therefore be
more unsightly than the efflorescence.
Can I cover the concrete with a material that does not try to bond with the
concrete? Something that can be laid on the top of the concrete? Ceramic
tiles? Is thin-set impervious to efflorescence? Vinyl tiles?
Would appreciate any suggestions? Thank you

if the root problem is water under the floor, why not install a french drai
n? either to a pump. or gravity to daylight, since a 3 car garage is pretty
big, run a couple leads from the rearof the garage towards the front, in a
reas you wouldnt be driving on. the walking areas.
no more water no more efflorescence.
wait say a year then if no more problems get the garage floor professionall
y coated with epoxy.
personally i think too many people put too much time ,effort and money tryi
ng to make their garage floor look pretty.
kinda like cleaning a toilet to eat off of........
garage floors are working surfaces.
although at home sale time making everything look perfect can net big bucks
